Wednesday Nov 11, 2015 17:10 PM | BY: T
PVMBG reported that during 1 August-4 November seismicity at Gamalama fluctuated, and was dominated by hybrid earthquakes and signals indicating emissions. 3 periods of increased seismicity were recorded during 3-5 and 11-19 August, and 8-22 October, though seismicity declined overall.
A sudden, small eruption from a fissure on the NW flank occurred at 19:53 on 8 September with no precursory seismicity, and produced a plume that rose 1 km. Gray plumes rose from 300-600 m the vent during 9-24 September.
White plumes rose from Main Crater and fissures on the E and NW flanks as high as 200 m during 1 October-3 November. The Alert Level remained at 2 (on a scale of 1-4); visitors and residents were warned not to approach the crater within a 1.5-km radius.
